Constellations
Constellations have fascinated astronomers for centuries. They are arbitrary formations of stars perceived as a figure or design, especially one of 88 recognized groups named after characters from classical mythology and various common animals and objects. Questions about the various constellations of stars are what this category is all about.

What are the five primary types of leases and what are their characteristics?
Hi dear TYPES OF LEASE AGREEMENTS Lease agreements are basically of two types. They are (a) Financial lease and (b)Operating lease. (c) Sale and lease back (d) Leveraged leasing and (e) Direct leasing. 15.5.1 FINANCIAL LEASE Long-term, non-cancellable lease contracts are known as financial leases. The essential point of financial lease agreement is that it contains a condition whereby the lessor agrees to transfer the title for the asset at the end of the lease period at a nominal cost. At lease it must give an option to the lessee to purchase the asset he has used at the expiry of the lease. Under this lease the lessor recovers 90% of the fair value of the asset as lease rentals and the lease period is 75% of the economic life of the asset. The lease agreement is irrevocable. Practically all the risks incidental to the asset ownership and all the benefits arising there from are transferred to the lessee who bears the cost of maintenance, insurance and repairs. Only title deeds remain with the lessor. Financial lease is also known as 'capital lease'. In India, financial leases are very popular with high-cost and high technology equipment. OPERATIIONAL LEASEAn operating lease stands in contrast to the financial lease in almost all aspects. This lease agreement gives to the lessee only a limited right to use the asset. The lessor is responsible for the upkeep and maintenance of the asset. The lessee is not given any uplift to purchase the asset at the end of the lease period. Normally the lease is for a short period and even otherwise is revocable at a short notice. Mines, Computers hardware, trucks and automobiles are found suitable for operating lease because the rate of obsolescence is very high in this kind of assets. SALE AND LEASE BACK It is a sub-part of finance lease. Under this, the owner of an asset sells the asset to a party (the buyer), who in turn leases back the same asset to the owner in consideration of lease rentals. However, under this arrangement, the assets are not physically exchanged but it all happens in records only. This is nothing but a paper transaction. Sale and lease back transaction is suitable for those assets, which are not subjected depreciation but appreciation, say land. The advantage of this method is that the lessee can satisfy himself completely regarding the quality of the asset and after possession of the asset convert the sale into a lease arrangement. 4)LEVERAGED LEASING Under leveraged leasing arrangement, a third party is involved beside lessor and lessee. The lessor borrows a part of the purchase cost (say 80%) of the asset from the third party i.e., lender and the asset so purchased is held as security against the loan.The lender is paid off from the lease rentals directly by the lessee and the surplus after meeting the claims of the lender goes to the lessor. The lessor, the owner of the assetis entitled to depreciation allowance associated with the asset. 5 DIRECT LEASING Under direct leasing, a firm acquires the right to use an asset from the manufacturer directly. The ownership of the asset leased out remains with the manufacturer itself. The major types of direct lessor include manufacturers, finance companies, independent lease companies, special purpose leasing companies etc ============================ *****for more detail go to this link http://du.ac.in/course/material/ug/ba/esb/Lesson_15.pdf by Vimal Raval
During summer in Sydney Australia would you observe Orion in the night sky?
Yes. It is visible at night in Sidney from November to February. During the winter in the Southern Hemisphere (May-July), Orion is located in the daytime sky and is not visible.
How big can a constillation get?
The largest of the 88 recognized constellations is Hydra, a long, slender, winding region of stars named after the many-headed sea serpent Hercules encountered in Greek mythology. Stretching from the northern hemisphere, where it borders Cancer, Hydra winds down to the southern sky, where it meets Centaurus.
Its Latin name is Lepus, which is the Latin word for "hare." The Hare Constellation lies just south of the celestial equator, and below the constellation Orion. It was one of forty eight constellations discovered by Ptolemy, and remains one of the eighty eight modern constellations.
What causes pulsating variable stars to pulsate?
When the core of a massive star is compressed during a supernova explosion, then collapses into a neutron star, it retains most of its angular momentum.
Since it has only a tiny fraction of its original radius, a neutron star is formed with a very high rotational speed.
A pulsar is a highly magnetised, dense neutron star emitting a beam of electromagnetic radiation.
Where is van maanen's star in Pisces?
Van Maanen's star is 2° of the star Delta Piscium, in the middle of the constellation Pisces.
Why is Cassiopeia upside down?
The Constellation of Cassiopea isn't always upside down. Depending on where you are and what season it it, we see the sky in different ways as the Earth continues its orbit around Sol (our sun) Look for Cassiopea 6 months after you see it upside down. It will be right side up.
What star pattern points to polaris?
The Big Dipper, or Ursa Major has two stars (sometimes called the pointer stars) which line up directly with Polaris. Those two stars, at the "lip" edge of the Big Dipper, are Dubhe and Merak. Merak is at the "bottom" of the Big Dipper, and Dubhe is right at the "lip".
How far awa is the constellation Sagittarius?
A "constellation" is better thought of as a direction away from the earth, not a physical object with a particular distance. Saggitarius's nearest star is Ross 154 at 10 light-years. It is too faint to be seen with the naked eye. Saggitarius is also the direction of the core of the Milky Way galaxy, about 27 thousand light-years distant.
Is polaris star on big dipper?
No, Polaris (the North Star) is part of the Little Dipper (which is part of the constellation Ursa Minor, "The Little Bear"). Polaris is the bottom-most star in the "handle" of the Little Dipper.
Why is Virgo considered a Spring Constellation?
In the Northern Hemisphere, why is Virgo considered to be a spring constellation?
A ship is a water-borne vessel larger than a boat, distinguished from a boat usually by being submersible.
Is Orions belt part of the southern cross?
No. It is a part of the constellation of Orion. The Southern Cross is separate to that.
Stars are blue because of their age and temperature. Blue is an indication of a young HOT star, when reddish color means the star is aging
Messier 89 (M89 or NGC 4552) is an elliptical galaxy in the constellation Virgo.
It's difficult to give a precise size to a galaxy as there is no defining boundary. However, estimates place the size between 100,000 -> 150,000 light years.
Zodiac sign of consetellation ursa major?
Ursa Major is a circumpolar constellation, i.e. it never rises or sets in the northern hemisphere (and never seen in the southern hemisphere).
The Zodiac constellations and signs go around the central band of the sky from tropic to tropic and crossing the equator.
So Ursa Major isn't a Zodiac constellation.
What are characteristics of constellations?
Constellations are arbitrary groupings of stars invented by people to break up different regions of the night sky. in most cases, the Individual stars in the constellations don't have any relation to each other. There is no such thing as "Mystical properties".
What are the largest constellations?
Modern astronomers break the sky into 88 designated star groups known as constellations. Here’s a quick breakdown of the five largest.
Constellations are typically measured in square degrees of the night sky; for comparison, a full moon covers about 0.2 square degrees.
- Hydra
Measuring at 1,303 square degrees, Hydra is the largest of the modern constellations. It’s visible in the Northern Hemisphere from January to May, but it’s best seen in the Southern Hemisphere.
HydraIt’s a string of nearly 20 main stars, and its brightest star, Alphard (also known as Alpha Hydrae), is about 177 light-years away from our sun. In artistic depictions, Hydra is typically represented as a serpent.
- Virgo
Virgo covers 1,294 square degrees. Its brightest star, Spica, is about 260 light-years from Earth, and it’s roughly 2,300 times brighter than our sun.
VirgoVirgo is visible from around the world. In the Southern Hemisphere, it’s most visible in the fall and winter, and in the Northern Hemisphere, it’s most visible in spring and summer.
- Ursa Major
Ursa Major means “great bear" or “larger she-bear” in Latin. It occupies 1,280 square degrees and includes the Big Dipper. The Big Dipper is an seven-star asterism, which is a pattern of stars with no officially recognized boundaries; Ursa Major, the constellation it’s part of, is comprised of about 20 stars.
Ursa MajorThe Big Dipper is one of the most well-known asterisms in the night sky. In the United States, it’s represented as a ladle, but in other cultures, its shape represents other items such as a plow, bull’s thigh, or a wagon.
The brightest star in Ursa Major is Alioth (the middle star of the dipper’s handle), which is about 82 light-years from Earth. The constellation’s second-brightest star, Dubhe, is about 2 percent less luminous than Alioth.
- Cetus
Sometimes called “the Whale,” Cetus stretches over 1,231 square degrees. The brightest of these is Beta Ceti, which is 96.3 light-years from Earth. As a whole, Cetus is a fairly dim constellation, and it’s most visible in the Northern Hemisphere in November.
CetusCetus gets its name from a misshapen sea monster in Greek mythology, which was sent by Poseidon to consume Andromeda. It’s also depicted as a whale-like creature with various heads attached to its body.
- Hercules
Hercules occupies 1,225 square degrees. It’s often represented as a human body—the body of Hercules, or Heracles, of Greco-Roman mythology.
HerculesFour bright stars make up the “torso" of this body: Pi, Eta, Zeta, and Epsilon Herculis. Hercules is visible in both the Northern and Southern hemispheres. In the Northern Hemisphere, it’s most visible from April through November.
The brightest star in the constellation is Kornephoros (also called Beta Herculis). It is about 139 light-years from Earth.
What season does the constellation Virgo appear?
The constellation Virgo is visible in all seasons, if you are between the latitudes of +80° and −80°. It is best visible at 9pm during the month of May.
How many stars are in the constellation Virgo?
there are nine main stars and then fifteen if you count his legs. go to this website and look at the star charts it helped me alot. http://www.astro.wisc.edu/~dolan/constellations/constellations/Leo.html
